Is it possible to run react-native application on an iOS device directly from the command line like we do on simulator with
react-native run ios --simulator "iPhone 5s"
Not directly from command line. But you can run it via Xcode.
$ <Path to React-Native project folder>/ios/.
You can build the project from command line using the following, in the
ios folder of the project
xcodebuild -scheme <RN project Name> -sdk iphoneos build
